Hi Phil
I've made some changes to a custom index but I'm not sure how to replace the old one. If I try to upload the new index (via bulk upload), I get a message saying "Duplicate song entries are not allowed ....." (can't remember the rest of it)

When we create indexes and we've done a lot of them we don't do a replace we just correct the entries that have issues using the Content Manager at my.igigbook.com. Usually there's a typo on a couple of entries even though we've taken time to review the index but we don't replace the entire index we just correct the entries that have problems.
